INDIANAPOLIS (AP) — The anti-tax Club for Growth is spending $1.5 million on
tight Senate races in Arizona and Indiana.

The group is spending $600,000 in Indiana on an ad hitting Democrat Joe
Donnelly for supporting congressional earmarks and $900,000 in Arizona
supporting Republican Jeff Flake for opposing the targeted spending.

The Club lifted Indiana Republican Richard Mourdock over U.S. Sen. Richard
Lugar in May’s primary and has bought sporadically in Indiana since then.

Club spokesman Barney Keller said the ad will show Donnelly is “just another
liberal” who supported Washington spending. Donnelly has pushed back against
that argument throughout the campaign, noting most recently that he voted
with Republican Speaker John Boehner 60 percent of the time.

Indiana’s Senate
battle has grown into the most expensive the state has ever seen.
